Determine the coordinates of the endpoint of a segment CE with one endpoint at C(3,10) and a midpoint at (1,6).
Disclaimer: This is 10th grade geometry.

Sahana E.

The midpoint is halfway from one end to the other. Just figure out ho wfar you've gone and go twice that far.
(1,6)  (3,10) = (4,16)
That is, you've added (4,16) to (3,10) to get to (1,6).
So, add it again:
(1,6) + (4,16) = (5,22)posted by Steve

Let the endpoint be (x,y)
so ..
(x+3)/2 = 1 and (y+10)/2 = 6
x+3 = 2 and y+10 = 12
x = 5 and y = 22
endpoint is (5,22)posted by Reiny
